Calculating Billing Issues — Subscription App Metrics

What is a Billing Issue?

A user enters a Billing Issue when Apple is failed to charge him. It's a flag for you that something is wrong with charges, it can be:

1. Outdated/wrong card.
2. Lack of money to pay for a subscription (#1 reason)

If you don't have a Grace Period for your in-app subscriptions a user will immediately lose access to the app's paid features.

How to calculate Billing Issues?

Apple/Google will let you know about Grace Periods via server2server notifications. Handle, store and process them to build custom views with Grace Period's analytics.

It's also important to calculate both a number of events of issues and a number of users in a Billing Issue state as it'll affect your app Revenue.
